Aerosol exposure from an ultrasonically activated (Harmonic) device.
OBJECTIVE
To determine the distribution and concentration of aerosol particles caused by an ultrasonic (Harmonic) scalpel during simulated surgical use.


METHODS
Prospective experimental analysis (Canadian Task Force classification II-1).


METHODS
Standard operating room.


METHODS
Lean pork, lean beef, water, and blood, and the Harmonic scalpel with ball, curved scalpel, and cutting tips.


METHODS
Real-time sampling of airborne aerosols was performed over 6-second sampling periods.


RESULTS
Blood and tissue particles increased significantly during use of the Harmonic scalpel. Local exhaust evacuation methods diminished these concentrations.


CONCLUSIONS
The Harmonic scalpel causes formation of bioaerosols that are composed of material of respirable size. When this device is used, a local exhaust system or smoke-evacuation method should be activated to reduce exposure to blood, blood by-products, and potentially infectious materials.
